The Muncie SH8S-M6509-A1PX (also referenced as SH8SM6509A1PX) is an SH8 Series air-shift power take-off built for high-torque truck applications. This unit falls between the TG and 82 Series in Muncie's lineup, filling demand where higher torque capacity is required. The integral air shift design keeps the air cylinder fully enclosed, which simplifies installation and protects the shift mechanism. The 8-bolt cast iron housing mounts securely to the transmission, and compatibility across 17 input gear sets means it fits most popular transmission applications. With 5 available speed ratios and 12 output shaft options, this PTO adapts to a wide range of hydraulic pump configurations. Call us to confirm proper fit for your application.
